We measure constant currency or the effects on our results that are attributed to changes in foreign currency exchange rates by measuring the incremental difference between translating the current and prior period results at the monthly average rate of the same period from the prior year. Unless otherwise stated, all period-to-period revenue, adjusted EBITDA and margin comparisons are on a constant currency basis.
When we refer to direct competitors, we mean companies that we compete with in vehicle claims processing.

I would now like to introduce Tony Aquila, our founder, Chairman and CEO.
Thank you, Kamal. Good afternoon, everyone, and thanks for joining us today.
We are pleased with our second quarter results which demonstrate progress from our continued investment in the business. Total revenue growth came in at 17.7% versus the prior-year period. Our adjusted EBITDA margin came in at 44.2%, up over 130 basis points year over year, including the impact of continuing headwinds in two of our major European markets. We achieved this margin while continuing to absorb recently completed acquisitions and increasing our investments in product innovation centers and new geographies now up to 61 countries.
